First, I hope this is an appropriate forum for this post, if not then I apologize and please let me know where it should go.

Recently I purchased some planes that had belonged to the seller's father. Among the planes was this one, it is just the airframe; radio, engine, and tank have been removed. Can anyone identify what this plane is? What is the purpose of the wing "vents" in front of the ailerons? If the photos look odd it may be because the plane is hanging upside down on the ceiling of my garage, and I rotated the photos 180 degrees.

WIngspan: 64"
Length: 48"
Wing covering is Monocote or some sort of plastic Cote. The fuselage is covered with fabric/dope.

The fuselage and tail surfaces look sort of like a Jodel D.9 "bebe" or maybe a later variant?
The wings don't have the same dihedral layout though..perhaps a simplified version?http://en.wikipedia.org/wiki/Jodel_D9

The wings have fixed "slots" to help air flow over the ailerons at higher angles of attack.

The Jodel had a polyhedral wing (multi-dihedral) IIRC.
It looks like a Tidewater Playmate to me. The leading-edge slots are, as stated, to enhance low-speed handling. The slots may have been created/bashed by the builder. The pic is of a full-size Stinson 108 that used slots.
